A fluid-energy mill for size reduction of a material includes a manifold defining a grinding chamber having a first radius extending from a center of the grinding chamber, a gas inlet, a feed inlet, and an outlet. The feed inlet is positioned such that the material enters the grinding chamber tangent to a second radius extending from the center and larger than the first radius.

A fluid energy mill requires considerable energy, primarily in the form of compressed air, which is the major cost component of the operation. To improve the economics of the fluid energy grinding, especially for hard solids, it is helpful to pregrind in a conventional mill and use the product as feed stock for the jet mill.

classifier .Fluid energy mill reduces the particles to 1 to 20 micron. To get a very fine powder,even upto five micron, the material is pretreated to reduce the particle size to the order of 100 mesh and then passed through fluid energy mill. Uses The mill is used to grind heat sensitive material to fine powder.

Fluid energy milling of ibuprofen was investigated and found generally hard to mill in its dry state due to its ductility and low melting point . In the study, ibuprofen crystals of different sizes (<40 μm or 50–250 μm) and morphologies (plate-like and needle-like crystals) were first produced by controlled crystallization.

Fluid energy or jet mill consists of a hollow toroid. A fluid, usually air, is injected as a high-pressure jet through nozzles at the bottom of the loop. High velocity of air creates zones of turbulence into which solid particles are fed. The high kinetic energy causes particles to collide with momentum for fracture to occur.

Working of Fluid Energy Mill. The feed introduced into the fluid energy mill is pre-treated to reduce the particles size to the order of 100 meshes. This enables the process to yield a product as small as 5 micrometers or less. Despite this, mills capable of output up to 40 kg/h are also available.

A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. Particles leaving the mill can be separated from the gas stream by cyclonic separation.
